Do you have SSI or SSDI? That might help a little. There are generally other things social service wise that might help you get out of the motel. If you have medicaid your caseworker should know about help for you; if you don't have medicaid it certainly sounds like you probably qualify for it and possibly some food assistance too. United way has something called 211 that tries to hook you up with appropriate assistance programs.

Your life just sounds so stressful. I'm sorry. Please keep writing and don't worry about length.
